Please Help! "+" symbol

I have a LG Nitro HD running Ice Cream Sandwitch 4.0.4. On the home screen there is a "+" symbol in the upper right hand corner. If you click this button you can access Apps, Downloads, Widgets, Wallpapers. Is there a way that I can take that plus symbol off my homepage? All I want is just apps and apps only on the homepage. I have looked everywhere and it seems like I can't find anything about this.
